Osx lion & cuda

[Robert Houllahan]

What machine is it in and what slot? Do you have a GT-120 as your GUI card? Resolve installs the CUDA drivers it needs to run.

Im on a 2010 2.8quad, using the ati 5770 for gui. Right now the cuda card is in slot one looks like it should be in slot 2.

[Joseph Owens]

Yikes, kind of looks like you’re using the cards flopped and getting the commensurate performance.

Yeah next time i will read the manuel before buggin you guys.

[Jacob Lanum]

well I flopped the cards to be in the right slots. performance has increased to 11fps with 1node with an s curve, disappointing to say the least. I was getting much better results with my 5770. Is this how well a gtx460 should perform?

[Margus Voll]

is 460 for mac ?

if not then you will probably not get any speed pump.

And if it is, did you delete the Apple.PowerSavejadada.kext thing ?
Get this first :
https://sourceforge.net/projects/cuda-z/files/cuda-z/Beta/CUDA-Z-0.6.133-SVN.dmg/download
This will show you the CUDA supported engines found in your ystem and test them for you.
If you dont see a drop down menu in the very beginning, your 460 is not for Mac of something else is wrong.
If you see it and the performance is doooh, you need to delete that Powersace kext and reboot.

[Sascha Haber] “t and the performance is doooh”

Do we have any benchmarks for what is “doohhh”?

I have a pair of GT480s running in a 16xCubix, and the Single Precision Float processing per GPU is around 1331 GFlop/sec. Double Precision around 168 GFlop/sec. The Host/Drive rate is about 5748 MiB/s.

What kind of numbers do you see?

I am away from my Q4000 system this weekend, but I’d be curious to run this gauge on it.
